Re: Need help with IH Transmission parts

Here are some #s, for IHC part # 27078H or Borg Warner WT163-16G maindrive gear. 9 21/32 overall length, pilot hole .983, 6 spline for clutch hub, 17 teeth on end for cluster. Does not say the diameter of 6 splines into clutch hub. Yours sounds like 1 1/4".Here is something interesting.ebay seller dmedennis has a maindrive gear part #WT251-16 Dodge #1091489.This gear is a wee bit shorter and has maybe 10 splines with 1 3/8 diameter. Pilot hole diameter may not be correct.Advance adapters sells pilot bearings or make a sleeve to bush up to size .984 and I think Fords about same age used 10 splines with 1 3/8 hub size/Next problem would the shaft fit thru your clutch release sleeve and will bearing ST243A fit shaft?My BW catalog does not say Dodge use T9 but IHC and Dodge shared some part #s for other transmission partsHave fun!

Thank you for all of the information you have come up with. I wonder what the chances are for finding an IHC #27078H or Borg Warner WT163-16G maindrive gear? Do you have any place you may suggest to look, or just keep watching Ebay? I am not in a hurry to find one, so have time to look.The one on Ebay from seller dmedennis is interesting. The 10 splines and probably 1 3/8" diameter would be the problem. A bushing could be made for the pilot shaft.Thanks again!

Left click, hold down and high light address. Let up. Right click down and choose "open in new window".That is the way Firefox browser works. FirefoxIf you have IE it would be similar I hope.You could copy and paste into new window too.Web site opened for me I just checked.

I found it now. I'm just kind of slow sometimes. That is an interesting parts list. Looks like it shows 2 different maindrive gears #62907H and 72978H could have been used. Wonder what the difference is between them. Both show 17 teeth and from the picture looks like they would be 6 spline, but wonder about the other dimensions. Thanks for finding and sharing that parts list.
